Application System

Our company not only provides TPO waterproofing membrane, but also
dedicates to integrated roofing systems. TPO single ply roofing waterproof
system includes mechanically attached roofing system, fully adhered roofing
system and ballasted roofing system.

Application Methods

For Mechanically Attached Roofing System

Before application, spread TPO membranes on substrate in advance.
Install TPO membranes perpendicular to steel deck ribs on the substrate without
distortions according to the flange. The overlapping width is 120 mm. The
minimum overlapping distance of membrane short side direction is 50 mm.
Fasteners are installed according to designed position. Hot-air welding is
adopted for laps with 40 mm welding width.

For Fully Adhered Roofing System

Before application, spread TPO membranes on substrate in advance.
Install TPO membranes on the substrate without distortions according to the
flange. The overlapping width should be more than 50 mm. Hot-air welding is
adopted for laps with 40 mm welding width. Professional adhesives need to be
used on both underside and substrate surfaces to adhere and maintain.

For Ballasted Roofing System

Before application, spread TPO membranes on substrate in advance.
Install TPO membranes on the substrate without distortions according to the
flange. The overlapping width should be more than 50 mm. Hot-air welding is
adopted for laps with 40 mm welding width.
